DRAFT-RIGGING FOR RAILWAY-CARS.

Application filed December 26, 1911.

i lllinois, have invented a certain new and useful Improvement inDraft-Rigging for Railway-Cars, of which the following s a full, clear,concise, and exact description, reference being had to the accompanyingdrawings, forming a part of this specifica-- My invention relates toimprovement in draft ri ging for railway cars.

One oiject ofmy invention is to provlde a draft rigging employing adraft yoke n which the side members of the yoke extend in a horizontalplane and commonly known as a horizontal yoke, and-a draft rigglng inwhich the cushioning mechanism or compression resisting device may.always be maintained in longitudinal alinement both in a horizontal anda vertical plane between the draft members of the railroad car, and thusinsure an even distribution of shocks. to all the parts of thecushioning mechanism, and an even transmission of shocks therefrom tothe draft members.

A further object is to furnish a draft rigging employing a horizontaldraft yoke n which effective provision is made for limiting the movementof the followers and the travel of the draw bar, and one having a11miting stop casting suitably constructed to permit the easy insertion.removal and replacement of the cushioning mechanism of the draftrigging.

A further object is to provide a railway draft rigging which may bereadlly at tached to the draft members and in which the shockstransmitted thereto may be evenly distributed alongthe draft members -ofthe car.

I have shown one form of means to prac ,tica-lly accomplish theseobjects, the means in part comprising a cradle in the'form of twosubstantially rectangular blocks of novel construction within and uponwhich the longitudinally movable cushioning member of the draft riggingis supported; the blocks composing the cradle further serving as lowerlimiting strip members for the followers to abut against.

The inventioif'consists in the novel construction of parts and devices,and in the novel combination of parts and devices here- Specification ofLetters Patent.

I .in shown and described, and more particularly pointed out in'theclaims.

In the drawings forming a part of this specification Figure 1' is aninverted plan view partly in-longitudinal horizontal section of a draftrigging embodying my inven-tion, and showing the parts in normalposition. Fig. 2 is a view similar to that inv Fig. 1 showing the partsin full buff. Fig. 3 is a vertical cross section on line 3, 3 of Fig. 1.Fig. 4 is a perspective view of one of the blocks or limiting stopmembers which forms one of the two members of the cradle, and showingthe inner face thereof. Fig. 5 is a view similar to that in Fig. 4 andshowing the outer face of the block or the face thereof engaging thedraft member and Fig. 6 is a detailed side elevation of one of the sidecastings with a block of the cradle applied thereto.

In the drawings 10-1O are the draft members or center sills. of arailway car, 11 the buffer block, v12 the draw bar carry iron, 13 thedraw bar, 14 a horizontal slot through the draw bar t receive thecoupler key 15, the slot 14 being elongated longitudinally of the drawbar. 16 is the horizontally disposed draft yoke comprisingthe sidememsecured thereto as by means of a rivet 20.

and an open front end for the insertion of the draw bar 13, the sides ofthe yoke adjacent the open front end being provided with horizontalslots 21 to receive the key 15.

Within the draft yoke 16 is the front follower 22, which normally abutsagainst the rear end of the draw bar 13, the rear follower 23..andbetween the followers, the 1011- gitudinally movable cushioning memberor compression resisting device 24, preferably a friction cylinder withcontained friction mechanism. The friction mechanism within thecushioning member may be of any suitable type. Side plates or stop casings 2525 are suitably secured to the draft members 10 as by means ofrivets 26-26. Slots 27 are provided in the side cast-ings and draftmembers and are longitudinally extended to permit the movement of theends of the key 15 therein upon movement of the draw bar. Longitudinallyex tending follower guides 2898 are suitably secured at their ends tothe lower portion of the side plates 25 by bolts or other suitablemeans, and preferably rest, intermediate their ends, upon the tie plate29, which is removably secured to the draft members 10, as by the bolts3030. The follower guides serve also to support the followers inposition within the yoke.

' Each of the side plates or stop castings is furnished with preferablyintegral main upper and lower front stops or shoulders 31 and .32respectively, and main upper and lower rear stops or shoulders 33 and 34respectively for the followers to abut against. The side plates are eachalso provided with a longitudinal median groove 35 .which the sides 17of the draft yoke 16 travel in reciprocating movement. Each side platealso has preferably formed integrally therewith upper front and rearintermediupper inner edge 41 shaped to conform with the adjacent surfaceof the cushioning member 24, and is furthermore provided preferably witha plurality of quadrilateral tapered bosses 42, preferably three innumber, arranged upon its outer vertical side 43. The bosses 42 of eachblock are received within corresponding quadrilateral tapered sockets 44provided in the adjacent wall. of each sideplate 25. Each block isprovided with openings 45 to permit the passage and the insertionthrough alined perforations 46 in the bosses, 47 in the side plates, and48 inv the draft members, of the bolts 49, each provided with 'asuitable head 50, and

threaded at its outer end to receive the nuts I 51 by means of which theblocks 4040 are tightly drawn into position. The bolts 49 serve to holdthe blocks 4040, to the side plates, and also assist in securing theside plates to the draft members.

In preferable construction the central socket 44 in each stop platereceives the head of. a rivet passing through the side plate and draftmember. The blocks 40-40 are attached, one to each side plate, and format the ends, lower, front and rear intermediate limiting stops orshoulders 52 and 53 respectively. The intermediate stops or shoulders36- 37-52-63 effectively limit the movement of the followers and thetravel of the draw bar, and prevent the within tain it in its properposition horizontally and vertically and hence in its position ofgreatest shock absorbing efficiency.

In the drawings, I have shown one form of a draft rigging embodying myimprovements, but I wish it to be clearly understood that the same ismerely illustrative, and that all changes and modifications arecontemplated as fairly fall within thescope of the appended claims.Claims 1. In a draft rigging for railway cars, the

combination with the thaw bar, draft yoke, followers and compressionresisting device, of side plates each provided with upper and lower mainand intermediate:stops,

the lower intermediate stops comprising a substantnilly rectangularblock, each of said blocks being removable.

2. In a draft riggingfor railway cars the combination with the draw bar,hori. draft yoke, followers, side plates and c ioning member, of acradle supper-til cushioning member, the side plates being provided withupper and lower front '5 rear main stops'for the followers to abutagainst and havingupper intermediate steps, the cradle forming lowerintermediate stops to' limit the travel of the draw bar. said sideplates being also each provided with longitudinal median grooves toreceive the draft yoke.

3. In a draft rigging for railway cars, side plates provided withremovable limiting stops, and means for securing said stops to the sideplates, each stop connarising a hollow member outwardly provided withperforated bosses, said hollow member having openings to receive saidmeans within the hollow portion thereof, and the side plates beingprovided with sockets adapted to receive saidbosses therein.

4. In a draft rigging for railway cars, the combination of side platesprovided with quadrilateral tapered sockets with removable stopsfor'said side plates, said stops having quadrilateral tapering bossesadapted to be received within said sockets.
